  Small Molecular Weight Organic Compounds in Living Tissues (NEET Biology Notes) Biomolecules in Living Tissues: Complete NEET study chart covering carbohydrates, amino acids, lipids, nucleotides, DNA and RNA. Chapter: Biomolecules -Dr.Sanjaykumar Pawar  Introduction Living organisms are made up of different types of organic molecules . These molecules are called biomolecules because they are essential for life. The four major groups of biomolecules are: Carbohydrates (Sugars) Proteins (Amino acids) Lipids (Fats and Oils) Nucleic Acids (DNA & RNA building blocks) These molecules perform different functions such as providing energy, building body tissues, storing food, and carrying genetic information. 1. Carbohydrates (Sugars) What are carbohydrates? Carbohydrates are the main source of energy in living organisms. They are made up of three elements: Carbon (C) Hydrogen (H) Oxygen (O) General formula: (CH₂O)ₙ Examples shown in the figure (A) Glucose Molecular Formula: C₆...

🌱 Nutrition and Food  1️⃣ What is Food? 👉 Definition: Food is an organic substance that gives us energy + building materials for our body. Simplest form: Glucose (a simple sugar) → like instant fuel for your body. Complex form: Starch (made of many glucose units) → stored energy. 🔎 Examples: Glucose → found in fruits, honey, energy drinks. Starch → wheat, rice, potatoes, bread. 📖 Story Trick: Imagine glucose is like cash 💵 (ready to use immediately), while starch is like money in the bank 🏦 (stored, needs to be broken down before use). 🧠 Mnemonic: “Glucose = Go now, Starch = Save for later.” 2️⃣ What are Carbohydrates? 👉 Definition: Carbohydrates are energy foods (main fuel for daily activities). Glucose + Starch belong to carbohydrates. They are the most common source of energy . 🔎 Examples: rice, bread, potatoes, cereals. 🧠 Mnemonic: C in Carbohydrate = C in Calories → "Carbs give calories." 📖 Story: Think of your body...
